A San Francisco woman is expected to spend two years behind bars after pleading guilty Monday to grand theft for bilking would-be apartment renters of $110,000, authorities said.

Rachael Marie Smith, 30, entered pleas to three counts of grand theft in San Francisco Superior Court and is to pay full restitution, authorities said.

Smith recruited victims by posting ads on Craigslist that offered to rent her apartment on the 5600 block of California Street near 18th Avenue, police said. In fact, authorities said, she was a tenant there.

Smith accepted would-be tenants' money for her Outer Richmond District apartment, then told them they couldn't move in immediately because her mother had cancer. About 18 people signed leases with Smith, and each gave her a $5,600 check for the first month's rent and security deposit, authorities said.

Smith then told them that they wouldn't be able to move in on their scheduled dates because her mother was sick and needed care, police said.

The scam came to light when one woman signed her lease, then complained to a co-worker that she couldn't reach Smith. The co-worker told her that Smith had taken her deposit on the same apartment and had given her the same story about a cancer-stricken mother, police said.
